Description

TECHNICAL FIELD

The present disclosed subject matter generally relates to various embodiments of a one-piece production/annulus bore stab with integral flow paths.

BACKGROUND

A typical wellhead structure for an oil and gas well includes a high-pressure wellhead housing secured to a low-pressure housing, such as a conductor casing. The wellhead structure supports various casing strings that extend into the well. One or more casing hangers are typically landed in the high-pressure wellhead housing, with each casing hanger being located at the upper end of a string of casing that extends into the well. A tubing hanger is also typically landed in the wellhead or a tubing head. A string of production tubing is supported by the tubing hanger. The production tubing extends through the production casing and provides a path for conveying production fluids from the formation to the wellhead. The area between the production tubing and the production casing is referred to as the annulus.

An oil/gas well also typically includes a production tree (also referred to as a Christmas tree) that is mounted on the high-pressure housing. The production tree includes a main production bore. Production bore stabs are commonly positioned between the main production bore of a production tree and the production bore of the tubing hanger so as to provide a flow passageway between those two production bores. This arrangement permits the production bore of the production tree and the production bore of the tubing hanger to be fluidly isolated from other bores and passageways within the completion system.

FIGS. 1-4 depict various aspects of one illustrative example of a prior art two-piece production/annulus bore stab 10. FIG. 2 is a cross-sectional view of the prior art production/annulus bore stab 10 taken through the axial length of the production/annulus bore stab 10. FIGS. 3 and 4 are transverse cross-sectional views of the production/annulus bore stab 10 taken where indicated in FIG. 1. As shown in these drawings, the prior art production/annulus bore stab 10 generally comprises an inner production stab body 11, an outer annulus stab body 12, an annulus T-ring 13, an annulus metal seal 14 and an annulus seal retainer 15. The production/annulus bore stab 10 also comprises a secondary annulus spacer 16, a secondary metal seal 17, a spacer 18, a primary metal seal 19 and a primary seal retainer 20. Also depicted is a set screw 21, a lower head cap screw 22, a set screw 23, a plurality of upper flow openings 24, a plurality of lower flow openings 25 and a plurality of flow channels 26. In general, the set screw 21 secures the annulus seal retainer 15 in position with respect to the outer annulus stab body 12 so as to secure the secondary metal seal 17 in position. The primary seal retainer 20 is adapted to be threadingly coupled to the inner production stab body 11 to retain the primary metal seal 19 in position and thereby provide a seal between an end 12A of the outer annulus stab body 12 and the outer surface 11A of the inner production stab body 11.

As shown in FIGS. 3 and 4, the outer surface 11A of the inner production stab body 11 has a plurality of channels or recesses 26 formed therein. When the inner production stab body 11 is positioned within the outer annulus body 12, a plurality of individual fluid flow paths 27 are defined between the recesses 26 and the inner surface 12B of the outer annulus stab body 12. Each of these fluid flow paths 27 is in fluid communication with one of the upper openings 24 and one of the lower openings 25.

The present application is directed to various embodiments of an improved one-piece production bore stab with integral flow paths.

FIG. 9 is a cross-sectional perspective view of the one-piece production/annulus bore stab 100 taken through the axial length of the production bore stab 100.

In general, one illustrative embodiment of a novel production/annulus bore stab 100 disclosed herein comprises a unitary, one-piece body 102 with a first end 104 and a second end 106. The body 102 has an outermost cylindrical surface 102S and an inner cylindrical surface 102T. Also depicted in FIG. 6 are a central bore 105 and an axial centerline 107 of the one-piece production/annulus bore stab 100. The physical dimensions of the one-piece body 102, e.g., the axial length 102L, outside diameters, the inside diameter of the one-piece production/annulus bore stab 100, as well as the radial thickness of the body 102 at various locations along the axial length 102L, may vary depending upon the particular application.

A plurality of individual and separate flow paths 103 are formed within the body 102. Each of the flow paths 103 has a first inlet/outlet 103A positioned at a first end (adjacent end 104) of the flow path 103 and a second inlet/outlet 103B that is positioned at a second end (adjacent end 106) of the fluid flow path 103. The first inlet/outlets 103A are positioned in or extend through a first cylindrical outer surface 102X of the one-piece body 102, while the second inlet/outlets 103B are positioned in or extend through a second cylindrical outer surface 102Y of the one-piece body 102. The outside diameters of the first and second cylindrical outer surfaces 102X, 102Y, respectively, may be the same or they may be different from one another. As indicated, in one illustrative example, each of the plurality of individual fluid flow paths 103 are formed or defined entirely within the one-piece body 102. Moreover, in one illustrative embodiment, each of the individual fluid flow paths 103 are fluidly isolated from one another within the one-piece body 102. As depicted, in one illustrative embodiment, each of the plurality of individual flow paths 103 extends for substantially the entire axial length 102L of the one-piece body 102.

The routing and configuration of the individual flow paths 103 within the one-piece body 102 may vary depending upon the particular application. In one particularly illustrative example, each of the plurality of individual flow paths 103 may comprise an axial length portion 103X having a centerline 103Y that is substantially parallel to the longitudinal centerline 107. In other applications, all or part of the one or more of the flow paths 103 may be oriented in a non-parallel relationship with respect to the longitudinal centerline 107. For example, at least portions of the flow paths 103 may be curved or otherwise non-linear with respect to the centerline 107 (or some other reference). Thus, the configuration or positioning of portions of the flow paths 103 with respect to the longitudinal centerline 107 (or some other reference) may vary depending upon the particular application.

With continuing reference to FIG. 6, in this particular example, each of the fluid flow paths 103 comprises a first flow path transition region 103S between the axial length portion 103X and the first inlet/outlet 103A, and a second flow path transition region 103T between the axial length portion 103X and the second inlet/outlet 103B. As also depicted, a line 103E extending through a center of the first inlet/outlet 103A and intersecting the flow path centerline 103Y at a first end of the axial length portion 103X defines a first included angle 125 that is an obtuse angle. Similarly, a line 103F extending through a center of the second inlet/outlet 103B and intersecting the flow path centerline 103Y at a second end of the axial length portion 103X defines a second included angle 127 that is an obtuse angle. In some applications, the angles 125, 127 may be approximately the same. In other applications, the angles 125, 127 may be different from one another. Additionally, the size, i.e., diameter of the flow paths 103 as well as the number of flow paths 103 may vary depending upon the particular application. With reference to FIG. 7, the illustrative one-piece production/annulus bore stab 100 disclosed herein comprises thirty-six flow paths 103, each of which have a diameter of approximately 6.35 mm (0.25 inches).

FIG. 10 is a cross-sectional view depicting the engagement and positioning of one end of the one-piece production/annulus bore stab 100 relative to another item of equipment 114, e.g., a tubing hanger or the valve block of a production tree. Also depicted in FIG. 10 is an elastomer seal 120, a seal 122, a seal spacer 124, a seal 126, a seal 128, an elastomer seal 131 and a seal retaining ring 130 that is threadingly coupled to the body 102. All of the illustrative seals and spacers depicted in FIG. 10 may or may not be present in all applications. The equipment 114 comprises at least one annulus fluid flow passageway or path 116 (only one of the annulus fluid flow passageways 116 is shown in FIG. 10). In one illustrative example, each of the one or more annulus fluid flow paths 116 is adapted to be in fluid communication with a radial gallery (or annulus fluid collection chamber) 116A. In some applications, the equipment 114 may contain a plurality of such collection chambers 116A, each of which may be fluidly isolated from one another. In one illustrative example, the annulus fluid collection chamber 116A may be defined (in whole or part) by the outer diameter (102X or 102Y) of the body 102 and the inner diameter 114X of the equipment 114.

In one illustrative example, the annulus fluid collection chamber 116A is adapted to be placed in fluid communication with one or more (and sometimes all) of the annulus fluid flow paths 103 in the body 102. The seal spacer 124 may comprise one or more openings that allow fluid to flow freely between the flow paths 103/the annulus fluid collection chamber 116A and the one or more flow paths 116 in the equipment 114. The illustrative embodiment of the one-piece production/annulus bore stab 100 discussed above may be manufactured using a variety of known manufacturing techniques, e.g., hot isostatic pressing (HIP), 3D printing, etc.

FIGS. 11 and 12 depict an embodiment of the one-piece production/annulus bore stab 100 wherein the individual flow paths 103 in the body 102 are formed by a process that includes drilling a plurality of intersecting bores in the body 102. FIG. 11 depicts the one-piece production/annulus bore stab 100 at a point where a plurality of axial bores 140 (only one of which is shown) have been drilled though the entire axial length 102L of the body 102 to define at least part of the axial length portion 103X of one of the flow paths 103 with a centerline 103Y. In some applications, the axial bores 140 need not extend throughout the entire axial length 102L of the body 102, e.g., the bores 140 may stop within the body at, for example, a location within the body 102 indicated by the dashed line 144 adjacent the end 106. In some applications, the axial bores 140 may be drilled in a single pass, e.g., from the end 104 through the end 106. In other applications, the axial length 102L of the one-piece production bore stab 100 may be such that each of the axial bores 140 is formed by drilling a bore from each of the opposite ends 104, 106 into the body 102 to form one of the flow paths 103, wherein these separate bores are substantially co-linear with one another (or otherwise in fluid communication with one another) and at least partially engage one another within the body 102.

Also depicted in FIG. 11 are first and second radial bores 142, 143 that are drilled to intersect with one of the axial bores 140. As indicated, in one illustrative example, the radial bores 142 and 143, respectively, correspond to the first and second inlet/outlet 103A, 103B of each of the fluid flow paths 103. In the depicted example, the axial bores 140 were formed prior to the formation of the radial bores 142, 143, but the order could be reversed if desired. FIG. 12 depicts the one-piece production bore stab 100 after plugs 150 were secured within the axial openings 140 at opposite ends thereof. The plugs 150 may be secured in position using any of a variety of known techniques, e.g., welding, providing a threaded connection between the plugs 150 and the axial bore 140, etc. Of course, in the example where the axial bores 140 do not extend throughout the entire axial length of the body 102, e.g., the case where they stop at location 144 (see FIG. 11), then only a single plug 150 would be required within each of the axial bores 140. With the plug(s) 150 installed, a plurality of individual flow paths 103 have been formed within the one-piece body 102. More specifically, in this example, each of the plurality of individual flow paths 103 (formed entirely within the body 102) comprises first and second radially-oriented flow paths 142, 143 that are in fluid communication with one of the axial bores 140, wherein the first radially-oriented flow path 142 terminates at the first inlet/outlet 103A and the second radially-oriented flow path 143 terminates at the second inlet/outlet 103B. In this particular example, a centerline of each of the first and second radially-oriented openings 142, 143 is positioned substantially normal to the flow path centerline 103Y of the axial bore 140. In the example shown in FIGS. 11 and 12, the bores 140, 142, 143 were formed by drilling the bores into the body 102. In other applications, such bores may be formed by other manufacturing processes, e.g., laser boring, etc.

As will be appreciated by those skilled in the art after a complete reading of the present application, one illustrative example of a novel one-piece production/annulus bore stab 100 with integral fluid flow paths 103 formed entirely within the one-piece body 102 disclosed herein provides some distinct advantages relative to prior art production bore stabs and annulus bore stabs. One problem associated with the illustrative prior art production/annulus stab body 10 discussed in the background section of this application involved maintaining seal integrity under operational conditions. That is, each of the inner production stab body 11 and the outer annulus stab body 12 are essentially two separate pressure vessels that may experience different thermal loads (e.g., different temperatures) when in service. Such different thermal loads may cause the inner production stab body 11 and the outer annulus stab body 12 to exhibit different amounts of radial and/or axial expansion under certain operating conditions. In turn, such differences in radial and/or axial expansion between the inner production stab 11 and the outer annulus stab 12 can cause problems with respect to maintaining the integrity of the seals, e.g., the primary metal seal 19 and/or the secondary metal seal 17, on the prior art production/annulus stab 10. The novel one-piece production annulus stab 100 may help to eliminate or at least reduce this problem due to its one-piece construction.

Another problem with the prior art production/annulus stab 10 was related to the required radial thickness of the inner production stab body 11 and/or the outer annulus stab body 12. That is, each of the inner production stab body 11 and the outer annulus stab body 12 are essentially two separate pressure vessels that must be designed for the unique loading conditions experienced by each of these separate pressure vessels during operation. More specifically, since there were no lateral seals between the fluid flow paths 27, the exterior surface of the inner production stab body 11 was subjected to an external pressure which tended to compress the inner production stab body 11. The radial thickness of the inner production stab body 11 was increased to resist this external pressure. Additionally, due to the two-piece configuration of the prior art production/annulus bore stab 10, the outer annulus stab body 12 was subjected to an internal pressure (the annulus pressure) at its inner surface due to the presence of the fluid flow paths 27. Thus, the radial thickness of this outer annulus stab body 12 had to be sufficient to accommodate this additional pressure loading. In contrast, the novel one-piece production/annulus bore stab 100 disclosed herein is essentially a single pressure vessel. Of course, that single pressure vessel will also have to be designed and sized for all loading conditions, e.g., internal and external pressures. However, due to the unique one-piece configuration of the production/annulus bore stab 100 disclosed herein, as well as the placement of the individual fluid flow paths 103 within the body 102, the overall radial thickness of the body 102 will typically be less than the combined radial thicknesses of the inner production stab body 11 and the outer annulus stab body 12. Other advantages of the various embodiments of the one-piece production bore stab 100 disclosed herein may be apparent to those skilled in the art after a complete reading of the present application.

FIGS. 13-16 depict various aspects of yet another embodiment of a production/annulus bore stab with integral flow paths disclosed herein. FIG. 13 is perspective view of this illustrative example of a production/annulus bore stab 100 disclosed herein. FIG. 14 is an enlarged cross-sectional perspective view of the first end 104 of the production/annulus bore stab 100. FIG. 15 is an enlarged cross-sectional perspective view of the second end 106 of the production/annulus bore stab 100. Unless specifically noted otherwise, the above descriptions of various like-number components or features apply equally to this embodiment of the production/annulus bore stab 100.

As before, in this embodiment, the individual and separate flow paths 103 are formed within the body 102. In this example, the production/annulus bore stab 100 comprises a flange 150 at the first (or upper end) 104. As shown in FIG. 16, the flange 150 is adapted to be coupled to another item of equipment 160, such as a valve block of a Christmas tree, etc. Also depicted is a radial gallery (or annulus fluid collection chamber) 151, an annulus fluid inlet/outlet 152, a production seal groove 153 and an annulus seal groove 154. Seals (not shown) will be positioned in the seal grooves 153, 154. Note that, in this example, the first inlet/outlet 103A of each of the individual flow paths 103 intersects the radial gallery 151, while the second inlet/outlet 103B of each of the flow paths 103 are positioned in or extend through the second cylindrical outer surface 102Y of the body 102. The item of equipment 160 also comprises a radial flow gallery 162 that is in fluid communication with the flow paths 103 in the body 102 and with one or more fluid flow paths 166 in the in the item of equipment 160. The internal bore 164 of the item of equipment is also depicted in FIG. 16. The flange 150 may be formed integral with the body 102 or it may be a separate component that that is welded to the remaining portion or the body at, for example, the location of the dashed-line 155 (see FIG. 14). For purposes of the attached claims, either of these configurations should be understood to constitute a one-piece body 102 for the production/annulus bore stab 100.

The particular embodiments disclosed above are illustrative only, as the disclosed subject matter may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. For example, the process steps set forth above may be performed in a different order.
